Abstract: Aiming at the iteration process optimization problem,information maturity was introduced.Nominal evolution function and effective evolution function which was based on expected rework probability of the information were presented.On this basis,the evolution process of output information maturity of one development activity was researched during its input information updating,and the maturity-driven overlapping iteration model of multiple coupling activities was set up.To verify the feasibility and flexibility of the proposed model,the development process of a car roof's stamping die was given as an example.The possibility of applying the model in different aspects such as product development process management and optimization was discussed.

Key words: iteration, information maturity, product development, rework, coupling, overlapping
